PA has been denying Mtn Lions in PA for a long time. but i do know they are here. ill have to check on the Game Commission site, but im sure if its being a "pest" it can be trapped and humanely killed or moved.
best i can say is call this number and report it 570-675-114
see
"Pennsylvania's last known wild eastern mountain lion was killed in Berks County in 1874. And, except for Florida, the eastern mountain lion is believed to have been extirpated from the East Coast by 1900. But, over the years, mountain lion sightings have been reported throughout the state."
i just woke up from a drunken stooper
